Abstract
The invention relates to an intelligent terminal application program installing file networking digital signature method. A developer uses a local signature card to sign a to-be-signed source file to generate a local signature file with a local end signature tool. The local signature file is sent to a signature server. After the local signature file passes data verification of the signature server, the local signature file is sent to a network signature terminal, a network signature card of a manufacturer is used for signature, a network signature file is generated and is sent back to the signature server, and network signature file is sent to the local end signature tool to generate a final signature file. Private key data is stored in the signature card and cannot be read, a private key of the signature card can be used for signature only after code verification is passed, the storing and using safety of the private key is improved, a signature server end verifies local signature data accuracy, local certificate validity, developer identity legality, and the manufacturer can authorize and control signature authority limit.
Description
Technical field
The present invention relates to application program installation file signature field, refer more particularly to a kind of application program installation file networked digital endorsement method.
Background technology
Along with the arrival of intellectualization times, the development of intelligent terminal (mobile phone, POS, TV etc. can install the terminal of intelligent application) is also more and more faster, and the development of intelligent terminal also brings constantly bringing forth new ideas of application software simultaneously.On intelligent terminal, user can realize more function by installing the application software oneself liked.But due to the application software diversity on network, the fail safe of intelligent terminal is also faced with great challenge.Usually different application software is designed by different software suppliers or Software for Design personnel, and the function of various application software is also not quite similar.In recent years, due to the appearance of many malicious application software, safe and reliable in order to ensure the application program be arranged on intelligent terminal, each intelligent terminal manufacturer starts on intelligent terminal, run signature authentication mechanism, and unsigned application program installation file cannot be played dress and run in intelligent terminal.
Current digital signature widely uses, digital signature is mostly to the signature of file by a software simulating, signature process is just at local operation, the personnel of any acquisition corresponding private key and digital certificate, private key and digital certificate can be used to sign to file, and signature process lacks examination & verification signer identity legitimacy.Private key storage security is low, and it is be stored on PC with document form that the private key data used in digital signature is preserved, and there is the risk be replicated, and lacks the examination & verification to signer identity legitimacy in the process of signature simultaneously.Owing to being stored in private key on PC and Digital Certificate Security ensures low, be easily replicated or poisoning infection, so others when illegal obtain private key and digital certificate, carry out illegal activities, the rights and interests of party can not get ensureing.
Summary of the invention
The object of the present invention is to provide a kind of intelligent terminal application program installation file networked digital endorsement method, developer's intelligent terminal application program installation file of signing is managed, thus guarantee that intelligent terminal manufacturer can authorize and management and control application program, the authority that the intelligent terminal application program installation file of developer to manufacturer is signed.
In the present invention, the application program of exploitation is carried out this locality signature by developer, be sent to signature server to verify, again the local signature file after verification is sent to manufacturer and network signatures terminal carries out network signatures, signed original document, local signature file and network signatures file carry out splicing the final application program signature file of generation by described local signature instrument, described application program just can download to terminal equipment and install, and ensures application reliability.
To achieve these goals, the following technical scheme of the present invention:
